Hello Rahul_Sharma,
I find it hard to understand your post. Please use punctuation to make your sentence more readable.

We decided to not give out full solutions on this forum on request. People usually just copy them without understanding them and lack the concepts taught in this level in later levels, usually returning to ask for more help.

What we can do is to help you with the code you’ve already written.
Just post it here (properly formatted as described in the FAQ) and we will tell you where you might have made a mistake. Be sure to include what you have tried, what do you think the problem is and of course where exactly the error happens.

I’m sure we can help you pretty fast with that information.
Greetings,
